p+1就是指针的值加1
&p[1]也是对指针的值进行加法运算,具体加多少,要看p的类型, 如果p是int*,那么地址就是加4
//实验代码
int a[33];
int *pa=a;
unsigned char b[33];
unsigned char *pb=b;
unsigned short int c[33];
unsigned short int *pc=c;
printf("sizeof(int):%x\r\n",sizeof(int));
printf("sizeof(char):%x\r\n",sizeof(char));
printf("sizeof(unsigned short int):%x\r\n",sizeof(unsigned short int));
printf("pa:%x,pa+1:%x\r\n",(int)&a[0],(int)&a[1]);
printf("pa:%x,pa+1:%x\r\n",(int)pa,(int)pa+1);
printf("pa:%x,pa+1:%x\r\n",(int)&pa[0],(int)&pa[1]);
